Smaller hang on the back filters work well.
One thing many folks setting up any planted tank seems tom over look, plant densely from the very start, do not wait for the plants to grow in!
Add some cheaper plants till the main display plants grow it and slowly remove the "starter plants" as needed.
Set up the substrate well, this is the main part of the non CO2 tank.
Feed the fish well. Add algae eaters, they will work many times more efficiently since the algae grow slower under non CO2 conditions also!

1" per gallon is a good rule of green thumb for fish stocking levels.
These tanks often look better on any given day than the CO2 enriched tanks.

The lower light and lack of gadgets and maintenance make these tanks much more efficent and cheaper for folks. If you leave for a week, the tank does fine as is. No worry.

Maintenance routines:

Dose once a week(optional)
Add evaporation top off water
Snip tops off plants that get too unruly.
Feed fish daily.
As dirt and growth get further out of hand, you can uproot and do a big hack and rearranging, do not do this more than once every 3-6 months. Do a water change right afterwards.
You may have to remove some algae manually every so often but the algae grows slow also.

That's it.
